The Workmanon coming in in the morning linsertsdiis. cardinto themachine, and operates alever or other suitable operating means, whichwill cause to be typed in the proper; place on the card the time atwhich '45 .the.workman comes in. Similarly on going out at noon, heinserts the card into the machine, and operates the lever, causing;thetime at which he goes out at noon 'to be printed or typed on the card;and so on for Means are provided whereby at a certain time a shift willbe made which will automatically cause the card to be positioned forprinting in a dil' fei'ent column. Means are also provided whereby theshift can be made manually'in case a workmancomes in late or if for anyother reason it is desired to print in a different column from thecolumn where the printing would naturally take place. I.

In order that the time of arrival and departure will be printed ondifferent linesoii ditl'ei'ent succeeding days, time-controlled meansare provided operable automatically once a day for causing thevertical-position of the card to be varied from day today, to cause thedate to be printed in the proper place on the card. All of the aboveprovisions are disclosed in the prior Crook application referred to Inthe present construction, however, improved time-controlled means areprovided for efiecting and controllingthemovement of the various partsof the recorder',-.such as the movement of the type carriage, themovement of the card rack, the movement of the clock hands, etc. I I iSpecifically, a powerful spring motor is provided for effecting themovement otjthe type carriage, the type wheels on theitype carriageandthe other power driven parts, and tlie'movement of these power drivenparts, particularly the -movenient of g'the type wheels, is limited to aquick intermittent or "periodic" moveinent (Or'ic'e a minute) by meansof an escapement which is allowed to operateperiodically. by means of atime-controlled motor. This motor, in the form shown comprises aclock,mechan ism having its own escapement, so thattthe primaryescapementgwhicli controls the powerful motor is, inturn, controlled bya second escapement which regulates the movement of the clockv mechanismreferred to.

The primary spring motor con'iprises two in some respects to theactuating- -t\vo spring drums used in phonograph mo- 05 hammer, aspringlost motion :connection is tois, one spring drum 52 being drivenfrom the other drum Tl in a yielding flexible manner. The inner ends ofthe springs 72 of both drums are riveted to the rotatable shaft 73, theouter ends of the spring being secured to the respective drum casings74, 75. The transmission above described from the motor to the maincountershaft is from the driven spring drum :'2.

The winding mechanism acts on the driving spring drum. This windingmechanism comprises the winding stem 76, a pinion 77 mounted on thisstem 76, a gear TS meshing with the pinion 77, and a gear 79 mesh- 'ingwith the gear-78 and mounted on the driving spring drum 71. In ordertoprevent the driving spring drum from unwinding a ratchet wheel 80 ismountedon the winding stem and engaged by a spring pressed pawl 81. V

In order that the driving spring drum may at all times exert asubstantially uniform pull on the driven spring drum, we providemeansand means whereby the internally threaded bushing 88 is controlledfrom the. driven drum 52 and the apertu'red bushing 89 is controlledfrom the driving drum 715. The

internally threaded bushing 88' is geared to the driven drum by means ofa gem-:91 rotatable with this bushing and meshing with the gear 92rotatable-with the driven drum. The bushing 89 having the squaredopening is geared to the driving drum througlrtheintermediate wind-inggear 78 previously re ferred to, which is mounted directly on thisbushing and meshes with the gear 79, and consequently thebuslxing isrotated whenever the -driviiig -drum' is rotated. From the above it willbe seen that a relative rotation in one -direction.- between the twospring drun'is will cause a shifting of a shiftable bar 86-inzonedirection; because of the thread for limiting the relative rotationbetween the two spring drums. provided for this purpose, the design issuchthat this relative rotation between the two drums is limited to ninerevolutions. This limiting meansrcomprises a geneva gearing In theparticular means-'- (Figs. 2 and 8), the single toothed gear 82 beingmounted on the driving drum, coaxially therewith, and the .mu-ltipletoothed gear 83 being mounted on the driven spring-- drum eccentricallylwith respect thereto. The multiple toot with one tooth 84 of peculiarformation sothat when its edge engages the circular por-- ed gear 83 isprovided tion of the sin le toothed gear, further rela-- tive rotationof direction is prevented. It-wi-ll be seen that the two gear members inthat:

this limiting tooth 84 will not only limit the winding up movement ofthe driving springdrum with respect-to the driven spring drum, but willalso limit the unwinding movement of the driven spring drum with Therespect to the winding spring drum. limiting movement in one directionisef fected by the engagement ofi the odd tooth: of the multiple toothedgear on one side of' the tooth 85 of the single toothed gear and thelimiting movement in the other direction is effected by engagement ofthe odd tooth 84 on the other side of the single tooth.

In order to indicate the relative positions of the two winding drumswith respect to each other, we provide an indicator comprising alongitudinally shiftable bar 86 which controls through suitabletransmission a suitable indicator 87 adjacent the dial of the clock andwhich shiftable bar is controlled by the relative position of the twodrums. This control by the two drums is effected by means of aninternal-ll threaded bushing 88 into which the end of the shiftable baris threaded, a second bushing 89 in which the squared end 90 of theshiftable bar is'slidable,

ed engagement betwee'n thebar and-the threaded bushing and relativerotation in the-opposite direction will cause sliding movement of theshiftablebar'in the opposite directi'on'. Thus, the-position of thisshiftable bar indicates the relative position of-the'two drums.

'llh'ertransmission from this shiftable bar 86-to-the-indicatimg member8'25 comprises a bracket 93 secured to the shifta'ble bar 86, a bell.crank lever-94 pivotally mounted at 95 and-having one :arm connected byapin and slotconnection with: the bracket 93am! a ilink 96 pivotallyconnected at one'end to the other 'armzoi the bell crank :lever 94 andconnected at its alpper end to' thesh-iftabIe indicating member 81: Theindicating member is providediwith two arms 97 and 98 suitably gnided to'canse' the indicating member to move'= up and" d'ow'nvertically; Thesearms are provided simply toguide the indi'catin meinberimd cause'it' tomove'smoothly and freely:

motor.

Thus far 'we have described the-powerful primary-'spring-motor whichfurnishes the power for the moving parts and have also described thetransmission from this primary motor to the main countershaft and fromthis countershaft to various driven mecha-- nisms.- We will now describethe means whereby a small time controlled motor controls and regulatesthe movement of the main countershaft which is driven firorn the primarymotor; This small controlling mo tor is mounted'onthe sideofi themainmotor; Its function is to control the movement of the main motor and theparts driven by the main motor; It does this by controlling ancscapement which permits a quick periodic' movement of the parts drivenby the main motonone movement per minute being permittledi The smallcontrolling motor is itself controlled by an escapement in the usualmanner of spring clock mechanisms.-

The'spring drum which drivesthe small controlling motor is kept wound upby the movement of the powerful primary spring motor. There are thusthree mechanisms directly associated with the spring drum of the smallcontrolling motor (1) the escapement which controls the periodicmovement of the primary motor and the parts driven thereby; (2) thecscapement mechanism which controls the movement of the spring drum ofthe small controlling motor in the usual manner of a clock escapement;and (3) the means for keeping the springdrum of the small controllingmotor wound up at a uniform tension comprising a transmission betweenthe powerful primary motor and thewspring drum of the small controllingmotor.

' \Ve will now describe in detail these three mechanisms, and first, themanner iii-which the escapement which'control's the primary motor isitself controlled 'by the controlling motor. A gear train connects thestar wheel 99 of this escapement with tlie main countershaft 17 so thatthere is a spring tension, tending torotate this=starwheel in t-hedirection of the arrow B in Figsi3 and 12; This gear train comprisesthe-pinion 48 and gearr49previously described, and a-pinion 100 meshingwithlthe gear 49,'and rotatable with, the star-wheel 99. -Thisistarwheel 99 is permitted -to move "periodically-once a minute by theescapeinentlever 101; This 'escapem'ent'leve i-i10.1is controlled by'a'; six

toothed star wheel 102 which is driven from the small controlling!inotoi or clock' inecha nism, the movement of'this'bontrolling clockmechanism being .so controlled that the 'sixtoothed: star wheel-makes: acomplete revolu tion every six minute's or .so th'at it ro'ta't'es' the.distance every :minute.

This movement continues until the sta r wheel 99 hastravelled far enough to move the follower 104 to release the teeth ofthe star wheel with which it is in engagement, whereupon the releasedstar wheel gives a quick movement under the action of the springtension. This movement of the star wheel causes one of its teeth toengage the follower 105, and the con from one tooth to the'o'thertinned-movement of thestar wheel forces the lower end (if-the escapementlever downwardly causing the pivoted dog 103 to slip past the point ofthe tooth with which it is in engagement, the/spring 106 permitting the70 1 necessary yielding of the pivoted dog. The movement of the starwheel 99 continues until the point of the tooth which engages thefollower 105 has forced this follower radially outwardly far enough topermit the 76 i and again causing the dogx103to engage and follow up atooth on the star-wheel 102. .:In': this i movement the dog 103 15 heldrigid 86 with respect to the escapement lever 101 by. .rneans of astop-pin 107- on the lever which is engaged by the dog.
